ELECTRODE BOX.

imputation med April 1s, 1927. serial No. 184,743.

This invention relates to watern purification and moreparticularly to anovei apparatus forpurifying water by electrolysis.

A primary object of the invention 1s to provide an electrode box havingnovel'features of construct-ion which fac1l1tate assembly and cleamng, and whose parts are easy to manipulate facture.

and economical to manu- Another object of the invention lis to provide a novel gasket for separating and insulating the plates from each other,

and

which will not swell or expand in width or length, thereby providing a fluid-tight box and insuring maximum efficiency at all times.

Av further object of the invention is to provide a novelv electrode platewhich permits of the electrical connection being made at either end thereof installed, that is, a plate which is reversible end for still be adapted to vreceive the plate is provide end and trical connections.

With the above regardless of how the it is proposed to elecand other objects in view which will more readily appear as the nature of the invention is better understood, the

same consists in the novel construction, combination and arrangement of parts hereinafter-.more fully described,

claimed.

illustrated and A preferred and practical embodiment of the invent1on 1s shown in the accompanying drawings,

in which Figure 1 is a vertical longitudinal sectional view of the improved electrode box.

Figure 2 is a vertical transverse sectional view thereof. l

of one of the is a longitudinal sectional view taken on the line 5 5 of Figure 4.

Similar reference characters. corresponding parts throughout figures of the drawings.

Referring to Figure designate the several 1 it will be observed that the construction includes in its organ-` ization a. base member designated as A and a top member B adapted ate with the alternately arranged plate units C and long circuitous pat generally to coopergasket and D to prov-ide a relatively h for the water in passing vthe electrode boX.

tributing the pressure and load incident toV on the top Imember The base A rests upon4 insulators 1 mou11t-.

ed in the support or carrying frame 2 and is provided at one end with an inlet connection?)V communicating with the chamber 4E formed by the upstanding wall 5'. The other end is equipped with a slip joint receiving boss 6 and a-discharge pipe `7 com-- municating therewith. The. edge portion of the base A is also surrounded by the gutter 8 which will carry any leakage or residual water when the device is taken apart to the drain opening 9.

Arranged along opposite side edges of the base A are a series of bosses 10 adapted to receive the shouldered elongated bolts or standards 11 which may be secured to the base by thev clamping nuts 12. These standards are of reduced diameter at their upper ends as indicatedat 13 and are surroundedA by insulating sleeves 14 thereby to insulate the members 15 .which are supported thereby.

The tops of the lstandards 11 are preferablyA providedwith nuts 16 to rigidly .unite the cross-heads with the standards, thereby to enable the cross-heads to withstand the clamping pressure placed onV the. elements of For the purpose of disthe manipulation of the top member B, a plurality of cross-head members 15 are employed, and, as will'be observed from Figures 1 and'2,` each cross-head is internally threaded to receive an Vadjusting screw 17.

These screws 'are provided at one end with` operating portions 18 and have their lower ends 19 swivelled in suitable bosses 20 formed B. It will, therefore, be apparent that by manipulatingthe screws 17 in the cross-heads, the, topB may be raised or lowered as desired to place clamping pressure on the gaskets C and plates D or to relieve such pressure to permit the readywithdrawal of the plates.

The top B is recessed asindicated 'at 21 to provide an outlet chamber 21 communieating with the outlet passage 22 and which in turn is connected with an outlet nipple 23 -having the elbow' fitting 24 attached thereto. The said fitting 24 is coupled with a special slip joint construction 25 which receives a bakelite pipe section 26 held in the same from the cross-head l the insulating bushings on the standardsV members Aand B, which as previously in-k dicated are` insulated from each other by that support the cross-heads. Also the provision of the bakelite pipek section 26 pre-Y vents electrolysis in the water lines and avoids grounding 'of the machine. i

By reference to Figurest and 5 ofthe drawings, it -will `be apparent that the insulating gasket units C? are of rectangular formation and include an insulating body 28 of hard insulating material preferably bakelite which has secured to the opposite faces thereof the relatively thinV and com paratively soft sections of segalite gasket material which insures the making of a wateretight connection between each gasketand plate. Y The construction described provides Aa laminated gasket wherein the bulk of the gasket is a body Aof hard insulation p which is not affectedby moisture, thereby preventing distortion of the. gaskets and zonsequent leakage.

The plates D' are provided at opposite Aends thereof with theline wire terminalr ears or connections 30 and near one end thereof are formed with the openings 3l.

Viren the alates are arranged to forni the electrode box the openings 3l in adjacent plates are disposed at opposite ends of the c ox so as to compel thel water to run back and forth between the Vplates and thereby become 'adequately subjected to the effect of the electric current.

When the device is assembled as shown in Figuie l', water enters 'the inlet connection 3 and makes its way into-the chamber e and from thence-it passes through the opening 31 of the lower plate D, and thencebetween the two lowermost plates D to the opening 3l of the second plate at the far end of the box. The water then continues torpass between adjacent plates until it reaches the upper 'chamber 21 and the outlet passage 22v whereuponv it is y conducted outwardly through the insulated discharge line 24, 25, 26, which communicates with the outlet passage 7 ofl the base.

If is desired to repaira `gaskety or clean the machine, it is onlyk necessary to manipulate the screws 18 to lift the top B- to thereby permit the separation of the plates and interposed gaskets so that-'either or both can be withdrawn longitudinally from the end of the machine opposite the purified water discharge connections. The slip oints in the dischargeor outlet line: permit of the movement of the bottom and top members A and B without separation of the parts forming the dischargeor outlet line. l i Without further descriptionit is thought that the. features and advantages of the invent-ion will be readily apparent I'to those skilled inthe art, andit will of coursel be understood that changes in the form, proportion vand minor details of construction may be resorted to, Without departing from the spirit of the invention and scope ofthe appendedvclaims. f I claim:- l g v1 An electrode boX including a chambered base, insulation members supporting the base, standards affixed to the base, cross head members carried by the standardsand insulated therefrom, a chambered 4top nadjustably suspended from said cross head members, an outlet connection carried by the top member and a slipjoint connection l carried by the base, and 'an'insulating tubing connecting the outlet of the topmemh ber with the slip joint connection on the base. 3

2. An electrode boX including a base, standards carried by the base, insulation sleeves carried by the uppery ends of the standards, a top member carried by the standards and insulated therefrom by said sleeves, means' for adjustably suspending the said top with reference to the base, a plurality of ported metallic electrodel plates and insulating gaskets arranged between the top and the base, an inlet .connection for the base, an outlet connection for the top, an outlet connection on the base, and` a slip joint including an insulating tubing between the outlet connection for the top and the outlet connection for the base.

In testimony whereof I hereunto afiiX my signature.
